Size: Floyd has fought a small number of bigger fighters than him. De La Hoya was a very close fight, he didn't do much to De La Hoya. De La Hoya thought he won the fight. He certainly didn't end it very hurt. In all of those fights Floyd was younger. The argument is that it stacks up now that Floyd is older.

Stance: tbh I think this is some bullshit. I think it's a general expression of "Floyd won't know how to deal with an MMA style", but without much more thought put into it.

Distance: same as stance.

A-side: Conor McGregor, as we've seen, is without a doubt the a-side when it comes to the fans. He is likely to represent the lion's share of fan support, which means he may likely represent the lion's share of PPV buys and ticket sales.

Clinch: dunno what Schaub is talking about. What I think is that McGregor might be better primed to push Mayweather out of the clinch, stopping him from resting during round.

Power: eh? McGregor has had 1 knockout? Have you watched his UFC career? He has knocked out almost everyone he's fought. He's had 2 decisions, 1 loss by submission and the rest wins by knockout. Personally, I don't see the big deal with McGregor's power. What he does have is very good time. He's good at chinning guys while they're moving, which magnifies the impact of the blow.
